The Z4000 I have is my main transformer.
I have a Lionel CW-40 that my younger brother got in a train set, but it doesn’t seem to provide sufficient power, especially for older 5 volt PS2 engines. I also have a Z500 brick and barrel jack adapter that I can run one track with, but I prefer the Z4000 so I can control conventional engines as well.
That also makes me want to ask another question. The last thing I was doing with my brand new TIU was passing power through it to run an older PS1 engine. I had the fixed channels turned off in DCS setup to avoid interference. Could this possibly have caused the failure?
